How to Cook a Perfect Prime Rib (2024)

How to Cook a Perfect Prime Rib (1)

Posted By: Darcy Maulsby, 02 Jan 12:48 am Category: Food, Iowa food

Would you believe me if I told you restaurant-quality prime rib is one of the easiest main courses to prepare, plus you’ll look like a gourmet chef in the process? Yep, it’s true.

Take it from this Iowa farm girl. I adore the taste of prime rib. So tender, so robust, and bursting with all the flavor and juiciness that makes each bite a little trip to paradise.

When my family asked me to cook prime rib for New Year’s Day dinner, I didn’t hesitate. The prep couldn’t be simpler, and the results are simply spectacular. When you serve this delectable prime rib, your guests (possibly even the vegetarians) will be begging for more.

Let’s get cookin.’

Select the right size roast. Allow at least 6 ounces of cooked, trimmed meat per adult. I cooked an 8-pound roast for our gathering, because I like to have leftovers. Beef and veggie soup, anyone?

Preheat the oven. Crank it up to 450 degrees Fahrenheit, and let it heat up for about 30 minutes. Also, you can remove the beef roast from the refrigerator at this time.

Gather your supplies. I recommend a metal roasting pan with a rack (like the one you might use to cook at turkey), olive oil, kosher salt, and fresh-ground pepper. Oh, and don’t forget to round up some soap and wash your hands thoroughly. We’re in the kitchen prepping food, after all!

• A side note about fresh-ground pepper. I LOVE my Kuhn Rikon® high-output ratchet mill. (Check out a video here to see it in action). I appreciate the easy and speed of these wonder gadgets, plus I adore the red color of my pepper mill, since it matches my kitchen. One more thing—don’t think you’re limited to filling it with black peppercorns only. After interviewing a chef years ago about how to amp up the flavor in any dish, I took his advice and use of mix of peppercorns, including black, green, red and white, which bring a different flavor to the party.

Season the beef. Follow the K.I.S.S. method (keep it simple stupid). Prime rib roast doesn’t need a marinade or any complicated preparations, since the meat speaks for itself. Drizzle olive oil on the roast. Spread it around the roast with your hands. Next, liberally rub kosher salt and plenty of fresh-ground pepper on the meat. I don’t measure—I just go with what looks right.

If you’re thinking about using an herb mix to season the meat, I say go right ahead. I like to use this homemade herb blend that I learned to make at my dear friend Shannon Latham’s Enchanted Acrespumpkin patch near Sheffield, Iowa. I’m a big fan of the recipe here forSave Summer in a Jar Herb-Salt Mixand used it on my New Year’s prime rib–divine! Thanks to my friend Mary Lovstad of Farm Girl Cook’n in northern Iowa for all the inspiration!

Dry rubs enhance any beef roast

Bake. Place the meat in a roasting pan that’s slightly bigger than the roast itself. I like a roasting pan and roasting rack, myself. Note–one side of the meat will have more fat on it. You want the fatty side facing up so the meat will baste itself as it cooks.

Finally, don’t add water to the pan, and don’t cover the roast. Just pop it in in the oven.

Timing is everything. How long does it take to cook a prime rib? Well, it depends. I like to start with a high temperature (450 degrees) for the first 30 minutes. Then I drop the heat to 325 degrees and allow about 13 to 15 minutes of cooking time per pound of beef.

DO NOT keep opening the oven door to check the meat. Just enjoy the tempting sizzle as the pan drippings appear during the first phase of cooking. Then savor the aromas as the beef finishes cooking over the next few hours.

A thermometer is the best way to guarantee the roast turns out exactly the way you want it. For an accurate reading, push the thermometer into the middle of the roast, making sure the tip is not touching fat or bone (or the pan). FYI–medium rare is about 130 degrees F. If that’s what you’re going for (confession–it’s my personal favorite), take the meat out of the oven when it’s around 120 degrees F. Remember that the roast’s temperature will rise at least 5 degrees after you remove it from the oven.

Let it rest. Warning—the prime rib will look incredible when you pull it out of the oven, but resist the urge to carve it right away. Let this meaty masterpiece rest for 15 or 20 minutes before carving to let the juices return to the center. Cover the roast with a “tent” of tinfoil. (If you’re at my house, be warned. My dog, Maggie the Red Heeler, is obsessed with tinfoil and will bark like a maniac when I tear a sheet of foil from the roll. Silly dog.)

With prime rib, it’s easy to satisfy everyone’s preference for doneness. The slices taken from the ends of the roast will be the most done, and the middle will be the least done.

Add a little something extra. When the roast is done make sure you use the drippings in the bottom of the pan to make gravy. Then you’ll have a head-start on the most flavor-packed beef stew you can imagine.

Next time I prepare a prime rib, I’m going to try Food Network Chef Bobby Flay’s idea for Prime Rib with Thyme au Jus. Here’s what he recommends:

Place the roasting pan on top of the stove over 2 burners set on high heat. Add the wine to the pan drippings in the pan and cook over high heat until reduced, scraping the bottom of the pan with a wooden spoon. Add the stock and cook until reduced by half. Whisk in the thyme and season with salt and pepper, to taste.

Tell me all about it.Bottom line? Do not fear cooking prime rib, even though this is a pricey cut. You can do this! When you do, be sure to leave a comment, e-mail me, post on social media and tell me all about it.

Did you know?
“Prime rib” is not a specific cut of beef but is actually a preparation method for a beef rib roast. If you know the standard meat roasting method, you can make prime rib out of several types of beef rib roasts, according to my friends at the Iowa Beef Industry Council.

Check out their handy Beef Roast Basics guide. You’ll find tips on how to know what size beef roast to purchase, how to carve meat like a pro and more.

More reasons why beef is good

With my background as an ag journalist, I love to highlight agriculture, especially Iowa agriculture. Why do we know beef here in the Heartland? Because Iowa is in the top 10 beef-producing states in America, terms of all cattle and calves (ranking #7).

Here’s a snapshot of Iowa’s beef industry, which is a powerhouse in terms of economic development and providing a safe, nutritious product that nourishes people around the world:

  • Total cattle inventory in Iowa (as of January 1, 2017): 3,850,000
  • Number of feedlots (2012 Census): 6,036
  • Number of cattle operations (2012 Census): 26,827
  • Number of farms with beef cows (2012 Census): 19,677
  • Iowa jobs directly related to the cattle industry (2015): 20,690
  • Iowa jobs indirectly related to the cattle industry (2015): 7,384
  • In 2015, Iowa’s cattle industry contributed more than $6.9 billion in business activity to Iowa’s economy.* Sources: Department of Economics, Iowa State University; Iowa Agricultural Statistics, U.S. Department of Agriculture; 2017 Cattle Inventory Report National Agricultural Statistics Service (NASS), Agricultural Statistics Board, United States Department of Agriculture (USDA).

Can’t get enough beef?
There’s no such thing as too much beef if you love it as much as I do. I think my friend Larry Irwin would agree, especially when it comes to hamburgers.

Make no mistake, the humble hamburger still reigns supreme from backyard barbecues to fast-food drive-ins across Iowa. But this Iowa icon also provides the perfect palette for culinary creativity when Larry Irwin showcases his Burger of the Month flavors in my hometown of Lake City. Get the story and the recipes here.

Also, get your grill on and build a better burger with my top tips.

Finally, I just had to share this photo below. My relatives in Webster County, the Walrod family, did extremely well on the show circuit this year with their beef cattle and took top honors with their Limousin cattle at the Iowa State Fair. Why not decorate the Christmas tree to celebrate a banner year?

Should you put water in the bottom of the roasting pan when cooking prime rib? ›

Placing the oven rack too high up will cause your roast to brown too quickly and burn! After 30 minutes in the oven, add a ½ cup of water to the bottom of the roasting pan. The key is to allow the onions to brown and caramelize while roasting, but not to burn and smoke in the fat.

Do you cook prime rib covered or uncovered? ›

Putting a dry rub on too early increases the likelihood of it being washed off or knocked loose before you get the beef cooked. Aside from seasoning mixes designed to go on up to one day before cooking for brining purposes, you'll only want the dry rub on the Prime Rib in time for the start of cooking.

Why do you salt prime rib before cooking? ›

The salt helps trap the heat to better cook the prime rib. “It conducts the heat and seals it,” says Betz.

Cook the Rib

Preheat the oven to 450°F. Place the roast fat side up, bone side down, in a large roasting pan. Cook for 15 minutes, then reduce the oven temperature to 325°F. This allows the heat to sear the roast, trapping the juicy flavors inside while the rest of the meat cooks.
